Side sleeping pillow

ABSTRACT

A pillow is shaped to encourage a sleeper to sleep on a side, rather than on the back. This is accomplished by providing a pair of arms extending forwardly from a head support. The arms are spaced apart less than the width of the sleeper&#39;s shoulders so it is uncomfortable for the sleeper to roll over onto the back. The arms are spaced from the edges of the pillow to provide for a side ramp, inclined upwardly toward the head support, to receive the forearm of the sleeper.

This application is based on provisional application Ser. No.60/652,131, filed Feb. 11, 2005, for which priority is claimed.

This invention relates to a pillow designed to keep an individual fromsleeping on the back, i.e. it is designed to keep an individual sleepingon one side or the other.

BACKGROUND OF THE INVENTION

Many individuals experience sleeping disorders and one in particular isa snoring condition known as Obstructive Sleep Apnea (OSA). OSA has beenreported by the National Sleep Foundation to affect approximately 71million people at least a few times a week. It is caused usually by theperson's airway narrowing in the upper track. Many factors cancontribute to this problem, but generally decreased muscle tone andfatty deposits in the throat are blamed. It is generally believed thatelevating a person's head and sleeping on the side can reduce oreliminate this snoring problem, hence a better night's sleep.

One archaic treatment is for the snorer to wear a tee shirt having atennis ball sewn in the back, the idea being that when the sleeper is onthe back, the tennis ball will ultimately cause discomfort whereupon thesleeper will roll onto the side. This is supposed to keep the sleeper onthe side but being awaken in order to roll onto the side is not veryrestful.

Disclosures relevant to this invention are found in U.S. Pat. Nos.4,850,067; 5,479,667 and 6,226,817.

SUMMARY OF THE INVENTION

In this invention, a pillow is provided that encourages a sleeper tostay on one side by making it difficult to roll over onto the back.Thus, this pillow construction does what medical professionals desirebut with a more comfortable result and minimum disturbance to thesleeper and a happier bedmate.

This is accomplished by providing a pillow that is too narrow for theuser to sleep on their back and is based on the observation that mostpeople are wider from side-to-side than from front-to-back. The pillowaccordingly has arms, abutments or side panels that are narrower thanthe sleeper's back. Thus, the only position the sleeper can normallyassume is on one side.

In one embodiment, the pillow has a wedge shaped design providing acenter section to receive an individual in a side sleeping position andtwo spaced arms or fixed blocks not permitting the individual to moveonto their back. The sleeper's head rests on an elevated portion therebyallowing the shoulder to be received in a comfortable manner in a slotformed by the pillow of this invention. The sleeper's face is supportedeither with the elevated head rest or on the arm/block extension area,depending on the sleeper's preference, as when the user sleeps in acurled side position. Preferably, both sides of the pillow of thisinvention provides a side ramp to allow an arm to rest in a sidesleeping position without interfering with the torso.

For a greater elevation or angle, one or more additional wedges may beprovided, to be added underneath the main center section of the pillow.In the alternative, a mechanical arrangement may be provided to increasethe inclination of the pillow.

It is an object of this invention to provide an improved pillowpromoting a user to sleep on a side.

Another object of this invention is to provide a side sleeping pillowincluding a side ramp for receiving the arm of the sleeper.

These and other objects and advantages of this invention will becomemore apparent as this description proceeds, reference being made to theaccompanying drawings and appended claims.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is an isometric view of the pillow of this invention, illustratedwithout an overlying cover in order to show its internal construction;

FIG. 2 is a side view of the inner core of the pillow of FIG. 1; and

FIG. 3 is an isometric view of the pillow of FIG. 1 to which has beenadded an external cover.

DETAILED DESCRIPTION

Referring to FIGS. 1-3, there is illustrated a pillow 10 having aninternal core 12 which may be slightly compressible foam, an inflatablemember or the like, and a cover 14 of a suitable finish material, suchas a soft foam sheet. The core 12 includes a generally horizontal planarrectangular base 16 which provides a waist and lumbar support assembly18 and a thoracic support assembly 20. The waist and lumbar supportassembly 18 includes a leading edge 21 of elongate wedge shape to mergesmoothly with an underlying bed surface.

A head support assembly 22 extends generally perpendicularly upwardlyfrom the base 16 and extends laterally to adjacent the sides 24, 26 ofthe base 16. Although the base 16 is illustrated as extending under thehead support assembly 22, it will be apparent it may terminate at afront face 28 of the head support assembly 22 provided the assembly 22is suitably thickened, i.e. the junction between the base 16 and thehead support assembly 22 may be vertical rather than horizontal asillustrated.

The upper surface 30 of the head support assembly 22 is preferablyhorizontal but may tilt slightly to the rear and provides a pair ofinclined sections 32, 34 adjacent the sides of the pillow 10 forpurposes more fully apparent hereinafter.

The pillow 10 manifestly can be made of different size to accommodatelarger or smaller individuals. An additional technique to this end is toprovide a removable block 36 in the head support assembly 22. With theblock 36 removed, there is a much shorter distance between the thoracicsupport assembly 18 and the surface that effectively supports thesleeper's head thereby providing a simple means to adjust the core 12 toaccommodate smaller individuals.

Extending forwardly from the head support assembly 22 are a pair of armsor panels 38, 40 that merge with the base 16 or, more specifically, withthe thoracic support assembly 20 and/or the waist and lumbar supportassembly 18. The arms 38, 40 are spaced apart a distance smaller thanthe width of the sleeper's shoulders and larger than the thickness ofthe sleeper's torso, i.e. the distance from the inside faces of the arms38, 40 are less than the width of the sleeper's shoulders and largerthan the thickness of the sleeper's torso. Although the distance betweenthe arms 38, 40 may vary somewhat, this distance is almost alwayseighteen inches or less. For a child's size pillow of this invention,the distance between the arms 38, 40 is typically less than one foot.

The arms 38, 40 may extend toward the waist and lumbar support assembly18 for a suitable distance, which may vary considerably. It is preferredthat the arms 38, 40 not be very long in order to minimize anyclaustrophobic sensations by the sleeper. The arms 38, 40 taper towardthe waist and lumbar support assembly 18 as shown best in FIG. 1 andtaper downwardly toward the thoracic support assembly 20 as shown bestin FIG. 2.

Although the pillow 10 may be made with one arm 38, 40 on an edge of thepillow, FIG. 1 shows a preferred embodiment where both arms 38, 40 arespaced from the edges of the pillow 10 in order so the user can sleep oneither side. Spacing the arms 3.8, 40 from the edges of the pillow 10creates an area between the outside of the arm and the face 28 for thesleeper's arm to fit. A side ramp 42, 44 is placed between the outsideof each arm 38, 40 and the face 28 to provide a rest for the forearm ofthe user. This is much more comfortable for the sleeper when compared tothe sitaution where the forearm rests horizontally on the base 16. Eachside ramp 42, 44 merges with the inclined sections 32, 34 of the headsupport assembly 22 thereby providing a long support section for theforearm and hand of the sleeper. The angle of the side ramps 42, 44 andthe inclined sections 32, 34 are preferably equal to provide a longmore-or-less continuous inclined section for receiving the forearm andhand of the sleeper.

In small batches, the pillow 10 is made by cutting and gluing blocks offoam material to provide the core 12 which is then covered with a softfoam cover 14. This approach is very similar to the manufacture of thepillow shown in U.S. Pat. No. 6,226,817, the disclosure of which isincorporated herein by reference. When larger production runs arefeasible, a mold may be made in which to cast a complete pillow. In thealternative, the pillow 10 may be of an inflatable member which alsoprovides a number of advantages. It will be seen that the foam cover 14not only provides a desirable surface texture, it also modifies theshape of the underlying core 12 to the extent of providing a roundedpillow 10 as shown in FIG. 3 rather than the angular appearing core 12as shown in FIGS. 1-2.

As shown in FIG. 1, if it is desirable to make a wedge shaped pillow inorder to elevate the sleeper's head, a convenient technique is to makethe base 16 of wedge shape or add one or more wedges 46 below the base16. In the alternative, a mechanical adjustment may be provided on anunderlying chaise lounge type support, as is common in outdoorfurniture.

Use of the pillow 10 should now be apparent. The pillow 10 is typicallycovered with a pillow case. The sleeper lies on one side, e.g. the rightside for purposes of illustration, with the head on the head supportassembly 22 in the area of the block 36. It will be appreciated that theface of the sleeper, or rather the side of the face, is supported eitheron the top surface 30 of the head support assembly 22 or on a topsurface 48, 50 of the arms 38, 40, depending on whether the sleeper ismore-or-less straight or is somewhat curled. The sleeper's rightshoulder lies in the corner between the thoracic support assembly 20 andthe face 28 of the head support assembly 22. The sleeper's right arm,from the shoulder to the elbow, lies adjacent the sleeper's torso. Theright arm of the sleeper can either be straight at the side of thesleeper or can bend at the elbow so the forearm lies on the side ramp 42with the sleeper's right hand on the inclined section 32. Thus, thelength of the arms 38, 40 is roughly the length of a sleeper's arm fromthe shoulder to the elbow, or shorter.

Although this invention has been disclosed and described in itspreferred forms with a certain degree of particularity, it is understoodthat the present disclosure of the preferred forms is only by way ofexample and that numerous changes in the details of operation and in thecombination and arrangement of parts may be resorted to withoutdeparting from the spirit and scope of the invention as hereinafterclaimed.
